Definitions

  • the invention relates to aluminum production plants using the Hall-Héroult electrolysis smelting process. It particularly relates to the lay-out of installations for such plants.
  • Metal aluminum is produced at the industrial level by igneous electrolysis, that is to say by the electrolysis of alumina in solution in a bath of smelted cryolite, called an electrolytic bath, using the well-known Hall-Héroult process.
  • the electrolytic bath is contained in pots comprising a steel shell lined on the inside with refractory and/or insulating material, and a cathode assembly positioned at the bottom of the pot. Anodes in carbon material are partly immersed in the electrolytic bath. Each pot and its anodes form what is often called an electrolytic cell.
  • the electrolysis current which circulates in the electrolytic bath and the liquid aluminum layer via the anodes and cathode parts, conducts alumina reduction reactions and also enables the electrolytic bath to be maintained at a temperature in the region of 950° C. through the Joule effect.
  • electrolysis halls which are electrically connected in series by means of link conductors so as to optimize the use of floor space in plants.
  • the pots are generally arranged so as to form two or more parallel lines which are electrically connected to each other by end conductors.
  • the electrolysis current therefore passes cascade fashion from one cell to the next.
  • the length and mass of the conductors are as small as possible in order to limit investment and operating costs, in particular by reduction of losses through the Joule effect in the conductors.
  • the conductors are also configured such as to reduce or offset, in whole or in part, the effects of magnetic fields produced by the electrolysis current.
  • an electrolysis plant comprises a series of flows, in particular flows of raw materials (alumina, carbon powder, pitch), flows of intermediate products (solidified bath crusts, anode assemblies . . . ), flows of end products (liquid and/or solid aluminum), flows of personnel (persons on foot or drivers of automotive equipment), flows of energy (in particular flows of electric energy), flows of demolition products (in particular from anode baking furnaces), flows of tooling, flows of pot components (such as cathodes or pot shells) and flows of maintenance equipment.
  • Some flows are essentially continuous (such as flows of raw materials), others are semi-continuous (such as flows of liquid aluminum, anode assemblies and solidified bath) and others are essentially discontinuous (such as flows of cathodes or pot shells).
  • the Hall-Héroult process causes consumption of carbon anodes during electrochemical reactions of alumina reduction; this consumption requires the regular supply of new anodes and the replacement of spent anodes from the electrolysis cells, which generate flows of new anode assemblies from the anode production sites towards the electrolysis pots, and flows of spent anode assemblies from the pots towards the reprocessing and recycling sites.
  • the applicant therefore set out to find plant arrangements which take into account these different constraints, which lead to a reduction in investment and maintenance costs, and with which it is possible to increase plant production capacity.
  • the subject of the invention is a layout for an electrolysis plant for the production of aluminum using the Hall-Héroult process, said plant comprising at least one liquid aluminum production zone H, characterized in that it comprises:
  • zone C which groups together the supply and recycling installations for the anode assemblies
  • zone B which groups together the supply and recycling installations for the electrolytic baths
  • zone A grouping together the liquid aluminum processing installations
  • transport means for the conveyance, between said operational zones and according to determined intermediate flows, of said heavy products such as liquid aluminum, anode assemblies and solid electrolytic bath,
  • a reserved transit zone also allows for greater control over operator working conditions and safety, in particular by restricting movements of personnel in this zone. It also provides for greater control over co-ordination of the process, over operational management and over environmental conditions required for certain heavy flows, such as the flow of spent anode assemblies removed from the electrolysis pots, which may require aspiration and effluent treatment means.
